BMW Z Series E85/6 (2003-2008)

When your CPV O-ring fails it causes a slow oil leak on the passenger side of the engine, making an oily mess that frequently resembles a rear main seal leak. Replacing the CPV with an upgraded o-ring ensures a long-term solution to this common problem. 

The factory o-ring over time fails from heat cycling and oil exposure due to the Buna rubber used in OEM o-rings, while the included Viton Fluoroelastomer is resistant to a much higher temperature to ensure prolonged life without leaking. 

The fuel pump is held into the tank with a retaining lock ring. Most people would take an extension or punch and tap out the ring with a hammer. But that's the wrong way to do it. You could damage the lock ring, or worse, the tank itself. This handy tool is toothed to match the lock ring and takes a standard 1/2 drive ratchet or small extension. Twist the ratchet and the lock ring comes un-done cleanly and smoothly. A hefty tool that pays for itself over and over. Fits most BMWs from 1988-2013. Also has application for MINI and Porsche.

This metal screw ring tightens down to old the top of the fuel pump or fuel filter assembly dependent on model of vehicle.

Together they make this job simple and easy and ensure a tight fit with a new ring. 

Every 60-80,000 miles, we recommend replacing your spark plugs to ensure your ignition system is running optimally. Over time carbon can build up around the head of the spark plug and decrease spark strength and effectiveness, leading to weaker fuel mixture detonation, misfires, and potential check engine lights. To prevent this, have put together our High-Performance Ignition Service Kits. These kits include new Bav Auto High-Performance Ignition Coils, new spark plugs, dielectric grease, and a BMW spark plug service label to keep track of when your spark plugs were replaced.

Bav Auto's Ignition coils feature core windings that have been modified to increase firepower and promote a faster, more efficient burn. This gives your BMW/MINI increased torque in the lower range of RPM and more horsepower in the upper range. Exact improvements depend on the current condition of your engine, but you'll definitely feel the difference. They'll also improve your fuel economy.

Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug.

To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new OE quality components, replacing any potential fault points in your ignition system for peak performance!
